The endoplasmic reticulum associated degradation (ERAD) is a process widespread in eukaryotes that enable cells to get rid of unfolded or unassembled polypeptides which jam the endoplasmic reticulum compartment. In order to improve understanding of the initial steps of the secretory pathway and their relationship, we focused on components of the ERAD ubiquitylation machinery in the yeast Yarrowia lipolytica. Two Hrd1p homologues, Hrd1p and Hrh1p, were identified in Y. lipolytica. A study of the fate of the heterologous CPY* reporter protein showed that YlHrd1p is involved in the elimination of this misfolded polypeptide, while YlHrh1p is not. Moreover, the different phenotypic pattern displayed by Deltahrd1 and Deltahrh1 cells suggests that the two putative E3 enzymes function in separate ways. Our results bring some evidence of a coupling between the ERAD pathway and the co-translational translocation process and show that studies in Y. lipolytica can give new insights into events that take place in the ER.
